Mr. P, gettin' older isn't for the weak-minded. You know your stuff, and you're anasset not only to this board but to your fellow racers. Personally, I would go to the track and watch the younger racers in the staging lanes & pits, and see who's a leaver and a natural. Buddy of mine did that with his car when he decided to get out of the seat. You might find a kid in school, but you might be arguing with him all the time because his teacher doesn't know what you know. Crew Chiefing a good kid in a car you know inside out would be cool and a noble way to pass on your skill & knowledge.
I'm probably nearing the time when I'll be done driving the drag car - I just don't run it as often anymore - but at 58, I'm probably going back to road-racing, at least track days: it lasts longer and is slightly more forgiving than having only 10 seconds to do everything perfectly.
